If you think of a bow (as in bow and arrow) placed in space in the proximity of a massive object. This bow for arguments sake is 100 km from tip to tip. Now replace the bow (wooden part and string) with what might be considered waypoints. The curved wooden part represents a straight line in curved space and the taught string would, I suppose, appear curved. If one person sets off along the 'wooden' path and simultaneously someone else sets off along the 'string' path what would be the outcome a) They would both arrive at the furthermost tip at the same time but the person who chose the string route was older? b) The person who chose the 'wooden' path arrived first? c) The person who chose the 'string' path arrived first? d) They both arrived together and their biological clocks where still in sync? e) The string route was shorter in distance but required more energy to traverse? f) none of the above? I'm not sure but I would think answer 'e' seems likely and probably 'c'
